Step 1 :Find the values of f(9), f(7), and f(3) using the given function f(x) = 4x - 3:
Step 2 :f(9) = 4(9) - 3 = 33
Step 3 :f(7) = 4(7) - 3 = 25
Step 4 :f(3) = 4(3) - 3 = 9
Step 5 :Plug these values into the given expression and simplify:
Step 6 :\(\frac{f(9)+f(7)}{f(3)+7} = \frac{33+25}{9+7} = \frac{58}{16}\)
Step 7 :Simplify the fraction and round to the nearest tenth:
Step 8 :\(\frac{58}{16} = 3.625\)
Step 9 :\(\boxed{3.6}\)
